Hello, I have found a bike that I am considering purchasing locally. The seller claims that the bike is a 2015 Sirrus Elite, carbon, and the original price paid for the bike was $3400 (?!?!). I would post pictures but I am a newbie with less than 10 posts, so I can’t yet. The bike does not have disc brakes, it has Shimano 105 groupset. The color is that darker gray with a white pinstripe. Comparing the pictures from the seller to pictures online, I believe it is a 2010 Sirrus Comp. The seller is asking $600 for the bike. I know this bike never originally cost $3400 and I’m not sure how they could call it a 2015 Elite when that is far from a 2010 Comp. Either way, they said they would take $550 for the bike. From the pictures it looks to be in good shape- nothing wrong that I could see. Any input is greatly appreciated. Thanks! Jim
